Here are my suggestions:
1. Make areas in the pink/purple boxes terra incognita which would reveal to nations bordering them, having territory nearby for sometime or by event
2. Green boxes: You can see info about who's the dominant power, their wealth(if a option like sending troops to raid them is present, or affect their troop quality), MP(how many troop they would spawn), relation with you, bordering country and other powers(those who dominate the nearby zones, you can have them fighting each other or attack your enemy), aggresiveness(likelyhood of them attacking you)
3. Black boxes: An advanced version of green boxes, as the zone is bigger, you may see "This zone is filled with patchworks of small countries", "Some medium sized countries carved up this zone, they are: NAME1, NAME2, NAME3, ....", "This zone is united under the rule of NAME" or "This zone is under the foreign occupation of NAME". Sometimes a powerful country in one of these zones may try to conquer its neighbors and sometimes one would collapse into smaller states for various reasons, and if the condition is flavorable for a certain nomad tribe, maybe you would see the Kara-Khitans, Jurchens or Uighurs marching into Kiev. Some flavor events could be added like Marco Polo(or random name according to in which country this event fired) brings great wealth/knowledge back to COUNTRYNAME!
